Category: Definition of Refractory Metal

The term ‘refractory metal’ is used to describe a group of metal elements that have exceptionally high melting points and are resistant to wear, corrosion, and deformation.

Industrial uses of the term refractory metal most often refer to five commonly used elements:
Molybdenum (Mo)
Niobium (Nb)
Rhenium (Re)
Tantalum (Ta)
Tungsten (W)

The identifying feature of refractory metals is their resistance to heat. The five industrial refractory metals all have melting points in excess of 3632°F (2000°C).
